Amazon SEO Agency: Services, Costs and Selection Criteria

An Amazon SEO agency owns the organic visibility of your products in Amazon search: keyword research, listing copy, backend attributes, images, and the ongoing measurement of whether that visibility turns into orders. The difference from a classic SEO agency is not effort, it is the ranking model. Amazon sorts results by which offer is most likely to be bought.

That sounds like a nuance, but it causes most disappointed mandates. Commission Amazon SEO as a copy project and you get better copy, rarely better rankings. Commission it as a revenue project and you need an agency that is allowed to talk about price, availability and reviews too.

What the agency actually owns

An Amazon SEO agency owns two numbers at once: how many relevant search terms your articles are served for, and how often an impression becomes a purchase. They belong together because Amazon uses the second as a signal for the first.

In practice that means keyword research and search term structure, the full listing build including the backend attributes shoppers never see, master data and catalogue hygiene, the image and A+ Content track, and measurement of impressions, click through rate and conversion per term over time rather than a single before and after screenshot.

An agency offering only the content track is a content agency. That may be exactly what you need, but the proposal should not say SEO.

Amazon SEO is not Google SEO

The key difference: Amazon has no backlinks and no domain authority, and the selling performance of the individual offer decides its position. Google evaluates how well a document answers a question. Amazon evaluates how likely a click turns into an order.

Three consequences follow. An article without stock loses its position and no copy work holds it. A price increase that hurts conversion costs ranking even when nothing changed in the listing. And reviews are not a soft brand topic, they are a direct lever on conversion and therefore on visibility.

What has to be in the proposal

A solid proposal scopes the work in articles, markets and languages, not in text modules. That is the fastest test of whether somebody knows the business. Asking for the number of ASINs, variants and target markets means calculating work. Quoting a flat fee for "listing optimisation" means calculating hope.

The scope should contain an indexing check, a demand and competitor analysis, the full listing rework including translation per market, an image and A+ concept, a measurement plan with a defined evaluation window, and a clear separation between organic and paid results.

That last point gets skipped most often. If campaigns run in parallel, revenue rises without any organic improvement, and afterwards nobody can say what was actually bought.

On the content side, the platform's own numbers are worth knowing. Amazon states on its own A+ Content page that basic A+ Content can increase sales by up to 8 percent and well implemented Premium A+ Content by up to 20 percent. That is a vendor claim rather than a guarantee, but it sets the order of magnitude. Both require Amazon Brand Registry, which in turn requires a trademark registered with a government trademark office such as the DPMA or the EUIPO.

How to recognise a good agency in the first call

The most reliable test is the order of the questions. A good Amazon SEO agency asks about stock, price, reviews and return rate before it talks about keywords. Anyone opening with a keyword list is selling a tool, not a diagnosis.

Five questions worth asking, and what the answer reveals:

• "What would you check first before changing anything?" Good: indexing, stock, price position, reviews, returns. Weak: title and bullets.
• "How do you measure success?" Good: organic visibility per search term plus conversion and revenue, with a defined window. Weak: rankings alone.
• "What happens if nothing moves after eight weeks?" Good: a named root cause analysis and a second approach inside the scope. Weak: more ad budget.
• "Who writes the copy and who publishes it?" Good: named roles, a defined approval path, a plan for catalogue errors. Weak: stays vague.
• "What do you need from us?" Good: access, product knowledge, an owner for price and stock, approval times. Anyone needing nothing is planning nothing.

One more signal is how the agency handles AI powered search on Amazon. Amazon launched the Rufus assistant in Germany as a beta in October 2024, rolled it out broadly in 2025, and renamed it Alexa for Shopping on 13 May 2026. For listings that means product data has to be complete and unambiguous enough for an assistant to repeat it correctly. An agency that has never raised this is working with the Amazon of 2022.

Cost and honest billing

Three billing models are common, and each fits a different situation. What matters is less the amount than whether the scope is measurably defined.

• One off project per assortment block: right when the catalogue was never built systematically. The result is a state, not a process.
• Monthly retainer: right with moving assortments, several markets or strong competition. You pay for monitoring and adjustment.
• Block of hours: right when you work in house and buy expertise selectively.

Two things do not belong in a contract. A share of ad spend, because the incentive points the wrong way. And a ranking guarantee, because no agency controls its clients' price, stock and competition.

Guaranteeing a position means guaranteeing something you do not own.

For transparency on our own side: we work with fixed fees and no percentage share of ad spend, and PPC management starts at 2,500 euros per month. What sits in which package is on our Amazon SEO agency page and in the services overview.

Agency or in house

In house pays off as soon as somebody genuinely owns the task rather than doing it on the side. That is the real dividing line, not company size.

In house works with a manageable assortment in one market, stable products and a team that touches Amazon daily. An agency earns its place with assortment breadth, several countries with their own language logic, a vendor setup with slow master data processes, or simply pattern recognition across many catalogues. The main value is rarely the writing. It is knowing that an article does not rank because it sits in the wrong category or because the main image breaks the image guidelines, not because of its title.

The third option is used too rarely. A one off audit with a prioritised action plan, then execution in your own team, is often the better entry point than an immediate retainer.

Red flags

Five patterns are reliable warning signs, because they all reveal the same thing: the provider is selling an output instead of an effect.

• A ranking guarantee or a promise of position one. Not controllable, so not credibly promisable.
• A percentage share of ad spend. The incentive points the wrong way.
• No question about stock, price or returns. The ranking model is not understood.
• Reviews offered as a service. Bought or incentivised reviews breach Amazon policy and risk account suspension.
• No separation of organic and paid in reporting. Every success report then becomes unfalsifiable and therefore worthless.

What to check yourself first

Three checks cost an hour and improve every agency conversation, because they front run the diagnosis.

First, indexing: search Amazon for your ASIN together with an important search term. If the article does not appear, it is not indexed for that term, and that is a backend issue rather than a copy issue. Second, conversion: compare the unit session percentage in your Sales and Traffic report against your best articles. If it sits far below, the problem is the offer, not the visibility. Third, the image track: open your product page on a phone and check whether the three most important buying arguments are visible without scrolling.

Anyone walking into a pitch with those three findings will know within minutes whether the other side is thinking along. If you would rather go through them together, get in touch. We will also tell you when your case belongs in house.
